Looking for a sad MLP fanfic

I'm looking for a good MLP fanfic. Can you help me out and give me some titles according to my tastes ?

I want a very sad story, with a bit of romance preferably. It must not contain any porn/R34, it actually disgusts me :/ It must not contain gore either (I mean, I don't mind some nose bleeding or a few scratches, I just don't want to read ponies being torn apart, mutilated beheaded and eviscerated throughout the whole story ! That's sick ******** IMO.).
I'd like preferably a rather long story, that longs several hours. I think longer stories give more emotions because we have more time to attach to the characters.

I've read these ones so far :

My Little Dashie, Past Sins (definitely the best story I've ever read, MLP or not ! Tthere's so much emotions throughout the whole story, it's very well-written ! I strongly recommend it to everyone, if not already read.), Memory Pending (very good story too ! and I'm definitely looking forward to the sequel), Secrets and lies, Hope in the storm.

At 2034 pages, 108,000 words, it is the single fanfic given the Legendary rank by Equestria Daily.

Well, its basically set in the fallout game universe. Takes place 200 years after the war between Equestria and the Zebras, which ended in balefire bombs detonating utterly demolishing the world. In Fallout Equestria, it follows the story line of Littlepip, a pipbuck (not pipboy) repair mare living in Stable 2 with a pipbuck as her cutie mark. After Velvet Remedy asks her to fix up her pipbuck and then leaves Stable 2, Lilpip (the nickname used during the story most of the time) follows her out into the wasteland to rescue her. She soon finds out that the wasteland is a harsh, bitter place and she wants to help it as best as she can.

Here is a link to the EQD page, I HIGHLY suggest reading it.

There are also sequels not written by the same guy, but are endorsed and liked by him such as Fallout Equestria: Project Horizons (Not currently finished, but you can still read the 2,700+ pages that have already been written [and yes, it is currently a lot longer than the original]). I highly suggest reading this as well.

I'm following your advice from a few months ago.
I started reading FOE a few days ago, and... Sweet Celestia ! This fic is beyond awesome. I mean : two of my favorites universes (MLP and Fallout) combined in one story, isn't that freaking cool ?
I really like the characters and their personalities, the story goes without real "dead" moments... And yeah, there are some kind of moments where I actually have feelings for the characters (for instance, I genuinely felt bad for Littlepip [Spoiler] when she had problems about craving for Mentats [/Spoiler].)
And the story, besides being a loooooong-ass one, is (in my opinion) well-written, and easy to read (I've got no issues reading it even though English is not my first language.

In other words, this story kicks ass ! I wish I took your advice sooner ! I'm currently halfway through the story, and I wish it never ends.
By the way, do you know if there are adventure stories like this, of the same length ? Or even half of it, it would even be great. I mean, 1 freaking million words ain't nothing !

Of course!
------------
Fallout Equestria Project Horizons is a currently on going spin-off of the original Fallout Equestria. Currently, it is around 2800 pages and is my personally favorite story. It follows Blackjack, a security mare that follows the trail of the mysterious EC-1101 trying to unlock its secrets while simultaniously discovering the dark secrets of the pre-war era and of the elusive character 'Goldenblood', the head of the OIA (Office of Interministry Affairs).

This one is by far my favorite fanfic of all time because of the intense storyline and characters that is even more on-depth than the original FOE.
------------
Fallout Equestira: Pink Eyes is roughly 200 pages and follows the adorableness of Puppysmiles (roughly aged 3 in human year comparison) after the pink bomb that goes off in Canterlot and she falls asleep for 200 years. When she awakes she finds herself in the ruins of her home and she must track down her mom whom said she would be back for her after work. Even with the horrible world around her, she seems like she doesnt see it at all, and just follows the trials of her mom.

This one is a bit shorter than the others, but it is a 'must read' for any fan on the FOE style of fanfic. It will 'tug your heartstrings' by sheer adorableness and darkness of what happens.
------------
I am currently reading Heroes, and so far it is a nice change of pace besides the whole 'must save everyone and be the best I can' and instead goes with 'survive at all costs'.

Oh yeah of course. I'm still watching every episode that airs (usually on the same day, but I never get to watch it live). I'm very much so still reading Project Horizons as well. I think I've actually bugged the writer once about the lack of updates.

That's pretty cool !
Do you know if PH is about to end ? I reached the end of what was written like 6 months ago so I think there's a couple new chapters now.
My opinion is that PH is as enjoyable to read as FOE, but some chapters are really hard to read (eg. without spoiling too much : friends who die, rape scenes, torture) so this is not for every reader !

Fine, enjoy your concert dude, it was a pleasure talking with you (like last year ), feel free to poke me if there's new chapters being released, or if you stumble upon an interesting fic (I'm still reading the **** out of those, I've stumbled upon a few good pieces)

Oh thank you, I'd better read this as soon as this is released, because I really liked the story (even if I felt a kind of lack of inspiration in the latest chapters, but this was great overall), and I was terribly frustrated to be unable to end such a looooong story

well, that, then there's pretty much all of 99, that one crusader filly that you know who killed (spoiler altert: she didn't really die), P-21, I'm fairly sure Rampage was (after she was found by the ghouls that turned her into a slave, many years before the events of PH) , you could include the raiders, but that's a given.

Ok, I'll agree that 99 was a rape factory, but Somber didn't go into details on that.
Yeah, but it was only briefly mentioned in a paragraph.
P-21 didn't go into talking about it much, but it is known.
And yeah, Rampage was, didn't talk much about it.
Lol raiders.

And same here, I wish the rest of the story would be instantly done so I could finish it, but I also want it to never end because I would have nothing to read.

Yes. I agree with you. Kinda curious as to how it ends, though. FO:E left too many open ends, in my opinion. Pip never gets to try bacon. That was my first rage at the end of it. And it wasn't until about 3 days later that i noticed something kinda important. (link soon to come to avoid spoilers)

Ahh, I agree :) Past sins was great :D It'd have to be second on my list of favourites :P I loved the ending.

I can't be of much help in the sad fanfic department (or any fanfic department :P I havent had time to do alot of reading. Not enough time. I've even put off reading the new chapter of Crisis: Equestria :P) I've only read about 5 fanfics in total.

The saddest I've read would probably have to be the Cupcake Chronicles. Thats sad in a way. I would recommend reading that, but it doesnt fit the criteria. the Author started experimenting. There's a bit of R34 in there (Although I don't really care much for rule 34 in fanfics, I do admit, the presence of that one scene sort of added to the feel of the story (cant go into more detail, spoilers)) Most people just skip that chapter though. Im not sure this story fits what you want. As i mentioned, it contains a scene with rule 34, and it has some gore in it (not that much to be honest, just some explanations. It is a sequel to Cupcakes :P)

one I can think of is "A Precious Rainbow"
its an alternative ending/story for "Cupcakes" were Applejack saves Rainbow from dying, but she looses her wings. she then has to learn to live without them. as for romance, Applejack helps rainbow and cares for her, so there's that kind and tender feeling between them.
(it doesn't describe Rainbow loosing her wings or anything like that, the only bad things seen is Evil Pinkie dying in the beginning and Rainbow having nightmares)

I don't think I saw it in the comments below, but Until You Met Her is one of my favorites. It's written in the second person, and some have said it was awkwardly done, but I loved it. And the story has a sad air about it, but it's got a happy ending, so it's pleasant. Hope you enjoy!
